Definitions

  • the present invention relates to a small sized (hereinafter called “miniature” or “mini”) hearing aid.
  • the invention relates to a miniature hearing aid having a microphone, an amplifier, a battery and a receiver, all contained in a housing.
  • Miniature hearing aids especially those worn on the users head--for example, worn in or behind the ear or built into spectacle frames--have an extremely limited space for installation of the required mechanical and electrical components. Therefore, constant efforts have been directed to installing the individual components required for the conversion and amplification of sound in a most favorable and space saving manner.
  • a mini hearing aid of the type to which the present invention relates is disclosed in the German Utility Model Patent No. GM 7,831,808.
  • This patent discloses a compact housing in which are packaged a microphone, an amplifier, a battery and a receiver.
  • the electrical components of this hearing aid are disposed on facing sides of two printed circuit boards, arranged in parallel within the hearing aid housing.
  • the thickness of the circuit boards had a direct bearing on the size of the housing so that it is desirable to reduce the thickness of these circuit boards.
  • too much of a reduction in the thickness of these boards leads to problems of stability and reliability.
  • 1,139,549 discloses a behind-the-ear hearing air in which the thickness of the printed circuit boards is eliminated as a factor in the external dimensions of the hearing aid.
  • openings or recesses are provided in the circuit board into which the electrical components are countersunk.
  • it is the thickness of the electrical components alone, rather than the thickness of these components plus the thickness of the circuit board, which determines the total constructional width of the amplifier.
  • An object of the present invention is to provide a circuit assembly for a mini hearing aid which has a minimum width dimension.
  • a further object of the present invention is to provide a circuit assembly comprising a printed circuit board and a plurality of circuit components in which the thickness of the circuit board is eliminated as a factor in the width dimension of the assembly.
  • a further object of the present invention is to provide a circuit assembly having a circuit board which is provided with openings for insertion of circuit components.
  • It is a further object of the present invention to provide a circuit assembly comprising a circuit board and a plurality of components arranged within openings in this circuit board in which the components are mechanically supported within these openings.
  • a miniature hearing aid including a microphone, an amplifier, a battery and a receiver all contained in a housing, wherein the amplifier comprises a number of electric circuit components and a circuit board having openings adapted to receive the components.
  • the opening is formed in the shape of a rectangle having at least one corner cut off at a 45° angle.
  • This configuration provides the additional advantage of compensating for size tolerances of the components to be inserted. This is because the corners of the components may contact different points along the slanted edges of the openings if variations occur in the lengths of the components' sides. Although such compensation is best achieved if two corners at opposite ends of one size of an opening are cut off, this effect is achievable even if only one corner of the rectangular shaped opening is cut off.
  • a further advantage of the openings with cut off corners according to the invention is that they make possible a certain degree of "centering" of the components so that the points of electrical connection of the components and the circuit board may be aligned. In this way, the correct insertion and alignment of the components in the circuit boards does not require any concentrated effort or attention on the part of the assembler. This is particularly true when the openings are provided with two cut off corners as indicated above. In this case, the center line of a rectangular shaped component which is inserted in a circuit board will be substantially aligned with the center line of the opening.
  • FIG. 1 is a perspective view of a hearing aid designed to be worn behind the ear.
  • FIG. 2 is a perspective view, on an enlarged scale, of the lower shell of the hearing aid illustrated in FIG. 1, into which the components of the hearing aid are positioned.
  • FIG. 3 is a cross-sectional view of a portion of the amplifier circuit board, in greatly enlarged scale, with a component inserted in an opening therein.
  • FIG. 4 is a top view of a portion of the amplifier circuit board, in greatly enlarged scale, having a rectangular opening for insertion of a component, with the corners of the opening at the ends of one long side thereof cut off at 45° angles.
  • FIG. 1 shows a miniature hearing aid designed to be worn behind the ear.
  • the individual components of the device are located in a housing comprised of an upper shell 2 and a lower shell 3.
  • the housing has an angle piece 6 attached to one end which encases a sound tube connected via a tube 7 to an ear olive 8. The external sound reaches the hearing aid microphone through a receiving opening 9 located in the angle piece 6.
  • the sound entering the opening 9 is passed to the microphone 12 by means of a sound tube 11.
  • Another sound tube 13 from a receiver (sound transducer) 14 leads to the tube located in the angle piece 6 and eventually to the sound tube 7.
  • the amplifier assembly 15 which is supplied with current from the battery.
  • the battery holder 4 is arranged to swivel about an axis 17. When the holder is in the position shown, the battery located in the space 19 comes in contact with the contact element 18. By swivelling the holder 4 in or out about the axis 17, the connection with the contact element 18 is made or broken, thereby activating or deactivating the device.
  • the amplifier assembly includes a printed circuit board 20 and components 21 positioned on or within it.
  • the center of a component 21, from which protrude connecting leads 22 and 23, exhibits a conical shape at its edges, as indicated by the wedge-shaped form extending outward on both sides.
  • the component 21 is wedged in position even though the board 20 has straight vertical walls in its opening 24.
  • the connecting leads 22 and 23 are clamped within the opening 24 and soldered to the printed circuit conductors 25 and 26, as indicated by the soldering material 27 and 28. The connecting leads thus prevent the component 21 from passing through the opening 24.
  • FIG. 4 shows the printed circuit board in top view with a rectangular shaped opening 24 for insertion of a component.
  • a component 21.1 which in this instance is a transistor with three terminals 30, 31 and 32
  • its upper corners contact the facets (slanted walls) of the cut off edges 40 and 41. This contact serves not only to hold the component in place, but also to center the component so that its terminals 30, 31 and 32 line up with the respective printed circuit conductors 33, 34 and 35.
  • these respective terminals and conductors are soldered together.
  • the dashed lines 42 and 43 indicate possible cross-sections of the component 21.1. As may be seen, the points of contact between the component and the cut off edges 40 and 41 of the opening 24 are displaced; nevertheless, the component 21.1 is securely supported within the opening and its terminals are aligned with the printed circuit conductors.
